Before deploying the application, it is important to configure deployment settings such
as JVM size, number of ackers, and number of workers. Because this topology uses a number of
joins and windows, you should increase the JVM heap size for the workers. Click the gear
icon on the top right corner of the canvas, and increase the number of workers (e.g: 5) and
increase the JVM heap memory (-Xmx3072m).
